本文重点研讨了车用、舰船用及应急发电用的涡轮增压柴油机过渡工况。在实践应用中,为改善柴油机瞬态特性采用了排气变压系统,减小涡轮通流面积;改变喷咀截面结构;并联动力涡轮装置;减轻柴油机、涡轮增压器本身的惯性、改善调速特性及利用外加能量装设了“空气喷气装置”等措施。并例举了部分取得实效的实例。
This article focuses on the transitional conditions of turbocharged diesel engines used in automotive, marine and emergency power generation. In practical application, to improve the transient characteristics of diesel engines, an exhaust gas compression system is adopted to reduce the flow area of the turbine; the cross-sectional structure of the nozzle is changed; the power turbine device is connected in parallel; the inertia of the diesel engine and the turbocharger is reduced; Speed characteristics and the use of additional energy installed “air jet” and other measures. And give examples of some of the actual results.
